Global energy network is an important platform to guarantee effective exploitation of global clean energy and ensure reliable energy supply for everybody. Global Energy Interconnection analyzes the current situation and challenges of global energy development, provides the strategic thinking, overall objective, basic pattern, construction method and development mode for the development of global energy network. Based on the prediction of global energy and electricity supply and demand in the future, with the development of UHV AC/DC and smart grid technologies, this book offers new solutions to drive the safe, clean, highly efficient and sustainable development of global energy. The concept and development ideas concerning global energy interconnection in this book are based on the author's thinking of strategic issues about China's and the world's energy and electricity development for many years, especially combined with successful practices of China's UHV development. This book is particularly suitable for researchers and graduated students engaged in energy sector, as well as energy economics researchers, economists, consultants, and government energy policy makers in relevant fields. - Based on the author's many years' experience in developing Smart Grid solutions within national and international projects. - Combines both solid background information and cutting-edge technology progress, coupled with a useful and impressive list of references. - The key energy problems which are challenging us nowadays are well stated and explained in this book, which facilitates a better understanding of the development of global energy interconnection with UHV AC/DC and smart grid technologies.

Global Energy Development: The Reality and Challenges

Abstract

Energy security carries socioeconomic implications. Global energy development is closely linked with resource endowment. The Earth is endowed with not only plenty of fossil energy, that is, coal, oil, and natural gas, but also with large quantities of renewable clean energy, such as hydro, wind, and solar power. Global energy development has traditionally depended excessively on fossil energy, resulting in a host of increasingly prominent problems, such as resource constraints, climate change, and environmental pollution, which severely threaten human existence and development. In response to the challenges of the situation, mankind must develop a good understanding of the new features of globalization on the economic development, resource allocation and environmental fronts to set the stage for secure, clean, efficient and sustainable development of world energy.

1. Global Energy Development: the Reality

Global energy development has gone through a course of evolution from firewood to coal and further to oil, gas, and electricity. Currently, world energy supply is dominated by fossil fuels as a gigantic motive force for economic development. Meanwhile, hydro, wind, solar power, and other clean energy alternatives are being developed and applied at increasingly high speeds to accommodate future energy demands, thereby playing an increasingly significant part in ensuring security of global energy supply and promoting clean energy.

1.1. Background

Total world energy consumption has maintained a long-standing growing trend with constant adjustments to the energy structure. In the mid-nineteenth century, firewood was the primary source of energy consumed by humans, compared to coal that accounted for a less than 20% share of total energy consumption. With the progress of the Industrial Revolution, the proportion of coal consumption soared significantly to more than 70% till the beginning of the twentieth century. In the twentieth century, the share of coal consumption plummeted along with the growing popularity of oil and natural gas. In the 1960s, oil surpassed coal as the most widely used energy source. The proportion of oil consumption peaked in 1973 before gradually falling after the two global oil crises from the 1970s to the 1980s. In the meantime, natural gas consumption rose constantly, while coal consumption rebounded slightly. It is most notable that profound changes in the global energy structure in the recent two decades have brought about a new pattern marked by equal predominance of coal, oil, and natural gas as well as rapid development of clean energy. See Fig. 1.1 for the changes in the composition of world energy consumption since 1850.

1.1.1. Energy Resources

Global energy resources include primarily fossil fuels (e.g., coal, oil, and natural gas) and clean energy (e.g., hydro,¹ wind, solar, and marine energy). Despite its massive fossil energy resources, the world is facing many practical problems, such as serious resource depletion and waste emissions, which are the legacy of large-scale exploration since the Industrial Revolution a couple of centuries ago. By contrast, clean energy is abundant, low-carbon, environment-friendly and renewable, with huge potential for future development.

By 2013, the world’s remaining proven recoverable reserves of coal, oil, and natural gas were estimated at 891.5, 238.2 billion tons, and 186 trillion m³, respectively, accounting for 52.0, 27.8, and 20.2%, respectively, of a total of 1.2 trillion tons of standard coal.² Based on the current average mining intensity, the global reserves of coal, oil, and natural gas can sustain 113, 53, and 55 years, respective...
